Na een mailgesprek met David Lichman (de clickerende PNH-instructeur, ik citeer “I believe that Parelli has moved dramatically towards positive reinforcement using food rewards – especially in the case of what they metaphorically call the Left Brained Introvert horse… the horse that doesn’t really want to move his feet for you, and has the “What’s in it for me?” attitude. Punishing or using negative reinforcement more violently often makes things much worse with these horses.”) dacht ik terug aan onderstaande test.

“It’s the Great Right Brain vs Left Brain Test … do you see the dancer turning clockwise or anti-clockwise?If clockwise, then you use more of the right side of the brain and vice versa.Most of us would see the dancer turning anti-clockwise though you can try to focus and change the direction; see if you can do it.

Dit is eigenlijk geen optische illusie, maar een voorbeeld van “inattentional blindness”. “It really has nothing to do with optics per se, but rather high-level cognitive (attentional) processing of visual stimuli. Many people don’t see the gorilla because their attentional resources are devoted to the given task, to the exclusion of other visual events. It may even be that for this particular task, conscious representations of black figures (and thus the gorilla) are actively inhibited.”
